Previous work showed that remotely sensed soil moisture fields exhibit multiscaling and multifractal behavior varying with the scales of observations and hydrometeorological forcing (Remote Sens. Environ. 81 (2002) 1). Specifically, it was determined that this multiscaling behavior is consistent with the scaling of soil hydraulic properties and vegetation cover, while the multifractal behavior ...
To meet the demand of regional hydrological and agricultural applications, a new method named near infrared-red (NIR-red) spectra-based disaggregation (NRSD) was proposed to perform a disaggregation of Soil Moisture Active Passive (SMAP) products from 36 km to 250 m resolution. The NRSD combined proposed normalized soil moisture index (NSMI) with SMAP data to obtain 250 m resolution soil moistu...
The importance of spatial variability of antecedent soil moisture conditions on runoff response is widely acknowledged in hillslope hydrology. Using a distributed hydrologic model, this paper aims at investigating the effects of soil moisture spatial variability on runoff in various field conditions and at finding the structure of the soil moisture pattern that approaches the measured soil mois...
Moisture is one of the most important factors that affects soil reflectance spectra. Time and spatial variability of soil moisture leads to reducing the capability of spectroscopy in soil properties estimation. Developing a method that could lessen the effect of moisture on soil properly prediction using spectrometry, is necessary. This paper utilises an external parameter orthogonalisation (EP...
a r t i c l e i n f o The aim of this study is to analyze the influence of the soil moisture sampling depth in the parameterization of soil emission in microwave radiometry at L-band. The analysis is based on brightness temperature, soil moisture and temperature measurements acquired over a bare soil during the SMOSREX experiment. A more detailed profile of surface soil moisture was obtained wi...
The effects of three levels of soil moisture content (10 - 12, 13 - 15 and 16 - 18% d.b.) and three levels of plowing depth (15, 20 and 25 cm) on draft, specific draft, and drawbar power requirements of a 3 - bottom disk plow and on soil pulverization and inversion in a clay loam soil were investigated. The experimental design was a randomized complete block design with a 3 × 3 factorial. Excep...

Multiple soil moisture products have been generated from data acquired by satellite. However, these satellite soil moisture products are not spatially or temporally complete, primarily due to track changes, radio-frequency interference, dense vegetation, and frozen soil. These deficiencies limit the application of soil moisture in land surface process simulation, climatic modeling, and global c...
In this study, biochar-amended soil cover was investigated to enhance reduction of CH4 emissions from landfills. This paper presents physical and chemical characteristics of biochar-amended soils. Specifically, moisture content, organic content, ash content, pH, particle size distribution, Atterberg limits, specific gravity, and permeability tests were conducted with biochar alone, soil alone, ...
